Common questions about Tenant Migrations
Q1: How are migrations handled for organizations with multiple geographic locations?
Migrating Microsoft 365 multi-geo environments can be tricky because of data residency and compliance requirements. Netwoven ensures a seamless transition through:
- Careful upfront planning
- Tool-based migration
- Strict residency alignment
- Minimal downtime
- Post-migration validation
Q2: How are third-party apps and custom solutions, such as Power Apps and Power Automate, managed during a migration?
Netwoven takes a structured approach to ensure third-party apps and custom solutions work seamlessly after a Microsoft 365 tenant-to-tenant migration.
Our process includes:
- Pre-Migration Assessment: Creating a detailed inventory of Power Apps, Power Automate flows, connectors, and dependencies to build a customized plan.
- Migration & Reconfiguration: Manually exporting and re-importing apps and flows, while re-establishing components like connectors, gateways, and connections in the new tenant.
- Testing & Validation: Conducting thorough testing to confirm apps and workflows function correctly.
- User Training & Adoption: Supporting end-users with training and change management to ensure smooth adoption.
- Ongoing Optimization: Providing post-migration support to fine-tune and enhance the new environment.
With this approach, Netwoven ensures your business-critical apps remain functional, compliant, and optimized throughout the migration process.
Q3: What tools are primarily used for tenant-to-tenant migrations?
Netwoven uses a combination of industry-leading tools and native Microsoft solutions to deliver smooth, compliant, and efficient Microsoft 365 tenant-to-tenant migrations.
Key tools include:
- BitTitan MigrationWiz – Reliable, all-in-one SaaS tool for migrating mailboxes, documents, and Teams workloads at scale.
- Quest On Demand Migration – Robust SaaS platform ideal for migrating Exchange Online, OneDrive, SharePoint, Teams, and directories (Active Directory & Entra ID).
- ShareGate – Widely recognized for SharePoint and OneDrive migrations with strong metadata, permissions, and version history preservation.

- Native Microsoft Tools – Native solution for Exchange Online and OneDrive migrations, complemented by third-party tools to overcome its limitations.
By combining these tools with proven methodologies, Netwoven ensures migrations are secure, efficient, and tailored to each organization’s requirements.
Q4: What is the recommended approach for tenant-to-tenant migrations?
Our methodology is structured into phases: assessment, design, pilot, production migration, and hypercare. Each step includes clear deliverables such as workload inventories, migration strategy documentation, pilot results, and final completion reports. This ensures transparency and control throughout the engagement.
Q5: What post-migration services are typically provided?
Every engagement includes a hypercare support period, typically two weeks after cutover. During this time, our team validates migrated data, resolves issues, and supports your IT staff in stabilizing the environment. We also conduct a retrospective to document lessons learned and opportunities for improvement.
Q6: How are migration risks managed during the process?
We identify risks early during assessment and map them to mitigation strategies. Common risks include domain cutover timing, throttling during migrations, and reauthentication of connectors. These are addressed through staging, pilot testing, and proactive communication with stakeholders.
Q7: Can we keep our existing domain, and will there be downtime?
Yes. Your domain can be moved to the new tenant, but it must first be released from the source tenant before being verified and activated in the destination. During this cutover, a short period of downtime is expected as DNS records update. With careful planning and pre-staging, most organizations keep downtime to a few hours or less, typically scheduled over a weekend to minimize disruption.
Q8: Which workloads have the least issues migrated, and which have limitations?
We support the migration of Exchange Online mailboxes, OneDrive, SharePoint, and Microsoft Teams across tenants. However, some items—such as 1:1 Teams chats, meeting artifacts/links, Planner tasks, and Stream (classic) videos—may have limitations depending on your environment and chosen tools. Our migration experts provide a clear workload matrix so you know exactly what moves, what needs re-mapping, and how to handle exceptions.
